Application filed June 2, 1914. Serial No. 842,432.

To all whom z5 may concern Be it lmown that I, THOMAS B. GRUN- wnLL, acitizen of the United States, residing at Prescott, in the county ofWalla lValla and State of l/Vashington, have invented new and usefulVimprovements in Fly-Traps, of which the following is a speciication.

rlhe invention relates to door or window screens, and more particularlyto the class of fly or insect trap screens.

l The primary object of the invention is the provision of a screen ofthis character wherein flies or insects will be caught and trappedtherein so as to eXterminate the same, and in this manner obviating thepossibility of the ies or insects gaining an entrance to a building orother inclosure.

Another object of the invention isy the provision of a screen whereinthe dead flies or insects will be delivered to the bottom of the screenso that the same can be readily removed therefrom, thus enabling thescreen to be rendered thoroughly sanitary.

A further object of the invention is the provision of a screen of thischaracter wherein the ies or insects can gain an entrance thereto, yetwill be prevented from an exit, thus trapping the flies or insects forthe killing of the same.

A still further object of the invention is the provision of a screen ofthis character which is novel in construction, strong, durable, andinexpensive in manufacture.

lVith these and other objects in view, the invention consists in theconstruction, combination and arrangement of parts as will behereinafter fully described, illustrated in the accompanying drawings,and pointed out in the claims hereunto appended.

ln the drawings :-Figure 1 is a front elevation of a screen constructedin accordance with the invention. Fig. 2 is a vertical longitudinalsectional view on the line 22 of Fig. 1. Fig. 3 is a fragmentaryvertical transverse sectional view through the screen. Fig. 4L is asectional view on the line 4-4 of Fig. 1. Fig. 5 is an enlargedfragmentary vertical sectional view through the screen.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring to the drawings in detail, the

screen comprises a door frame A, which is preferably made from wood,although it may be made from other material, and is of the usualconstruction, having fixed to opposite faces wire meshfabric 5 and 6respectively, which extends throughout the entire length of the frame toform a space 7 therebetween. The outer wire mesh fabric 5 or 6 is cut toform a series of slots, the longitudinal edges thereof being inturned toprovide flanges 8 which are spaced from each other to provide entranceslots so that flies or insects crawling upon the wire mesh fabric 5 or 6will pass through the slots to the interior space 7 of the screen to becaught therein.

Arranged within the space 7 centrally of the frame A is a tubular columnor pipe 9 which has its opposite ends fitted in head and foot bracemembers 10 and 11 respectively, the latter being secured to the verticalportions of the frame A and serve as partitions to form traps 12 at bothends of the screen, which are in communication with each other throughthe column or pipe 9 so that flies trapped in the upper space 12 will bedelivered through the column or pipe 9 to the lower space 12 within thescreen.

Formed at intervals in the brace member 10 at the head of the screen areapertures 13 which communicate with cone-shaped thimbles 14 suitablyfixed to the said member 10, and form restricted entrances to theuppermost space 12 from the space 7 between the wire mesh fabric onopposite faces of the frame A of the screen so that flies within thespace 7 can pass through the thimbles 14. into the uppermost space 12 tobe trapped therein. Now, assuming that flies have been trapped in theuppermost space 127 on the jarring or the opening and closing movementof the screen the flies trapped in the upper portion thereof will beconveyed through the column or pipe 9 into the lowermost space 12 of thescreen so that the dead flies or insects may be conveniently removedfrom the latter after the trapping thereof.

At the front of the frame A near the lower end thereof is provided adoorway 15, the same being closed by means of a swinging gate or door 16provided with suitable catches 17 for sustaining it closed, and throughthis doorway 15 access may be had to the lowermost space 12 for theremoval of the dead flies or insects therein. In this manner the screencan be rendered thoroughly sanitary. It will be apparent that the iiiesand insects will be trapped by the screen, and that the same will beprevented from gaining entrance to a room, building or other inclosure.Furthermore, by the trapping of the flies as hereinbefore set forth thesame will be eXterminated.

From the foregoing it is thought that the construction and manner of useof the device will be clearly understood, and therefore a more extendedexplanation has been omitted.

What is claimed is :w-

An insect trap comprising a frame, wire mesh fabrics secured to theopposite side of said frame, and constituting front and rear walls, oneof said walls being provided with entrance slots, partitions mountedbetween said walls adjacent the opposite ends of said frame and formingtrapping chambers, said partitions diverging from their medial portion,the upper partition being provided with restricted openings, and a pipehaving the opposite ends thereof conneoted to the medial portions ofsaid partitions and forming a communicating passage way between saidtrapping chambers.

In testimony whereof aix my signature in presence of two witnesses.
